## Chemistry 9th Edition

The $K$ value indicates the relative concentrations of the products to the reactants, so the larger the $K$ value, the more concentrated the products are relative to the reactants. This reaction is likely a good source of products.
Concept explained in-depth in textbook. The reaction has an equilibrium constant equal to $1.3\times 10^8$ which is quite large, meaning that there is a large concentration of products at equilibrium.
